If I'm honest, the text you used in the example is literally one of the worst possible examples you could have chosen to highlight why you believe unfurling by default is bad.
If you think about it from a user's perspective; does it not make sense for them to get a brief look at the description of the addon you're recommending?
Ignoring the fact that all your addon descriptions have the same text on top, so it tells people literally nothing, for any other addon they would see a brief introductory text that describes the addon in question.
If you were reading those titles, ignoring the description, you might be wondering "what does 'Mail' do? XenForo already lets me send email." or "what does 'User Tagging' mean?"
Without unfurling, users have to click those links to find out.
With unfurling, they get to instantly see what all of them do at the briefest glance and they can make a decision whether they are actually interested.
The OP offers no explanation as to why it's a bad thing to see additional information to go along with links you post. As a result, if it wasn't already obvious, I strongly disagree with the OP.
